The plate 8 will preferably be made V whole, provided at one end with an oval or detachable for the reason that it lessens the 7o elliptical plate, 2, which is bolted to the end cost of manufacture; but as it is only for the of the retort, as is usual. The body of the inpurpose of affording a bearing for the spring jector 1 is hollow from end to end, as is clearly 9, its construction may be varied considerably shown in Fig. 1, and screwing into the inner without departing from the spirit of my inend is a discharge-nozzle,3, (shown in Figs. 1 vention. and 2,) said nozzle 3 having a tapering or coni- The worm-wheel 5, hereinbefore referredto, cal discharge-orifice.

The as shown in Fig. 1. body 1 is closed at its outer end by a cap, 4, The key may be made fast to the worm-wheel 3 5 which is provided with suitable packing- 5 or to the valve 7, as desired; but in any glands to prevent the escape of steam. It will event the construction should be such as to 8 5 be noticed, however, that the end of the body permit the valve to slide freely back and forth l, into which the cap 4is screwed, is enlarged through the worm-wheel, in order that the somewhat in diameter, this construction forinspring 9 may operate to keep the valve to its 4o ing a shoulder, 27, between which and the inseat as the valve expands or contracts. The r ner end of the cap 4 a wor1n-whee1,5, hereinworinwheel is prevented from moving upon 9c after referred to, is held in position. the valve 7 by reason of'its being clamped be- Forined in the body 1, about midway between the shoulder 27 and the inner end of tween its ends, is the steam-inlet 6, (shown in cap 4. This wheel 5 meshes with a worm, 10, Fig. 1,) the body 1 being also provided or which is mountedin atransverse enlargement, formed with a slight circumferential swell or 23, of the shell or body 1, as shown in Figs. 1 95 enlargement, 17. and'', the shaft of said worm being extended 7 indicates a hollow valve, which is turned outward and provided with a hand-wheel, 11, to iit accurately within the shell 1, said holby which it may be turned.

About midway of the length of the hollow seen that by turning the stem l2 so as to bring its tapering nose 22 into or out of the seat formed for it in the end of the hollow Valve 7 the amount of steam discharged from said hollow valve may be accurately regulated.

It will also be observed that by turning or rotating the screw 10 and worm 5, and consequently the valve 7, to which the worm is secured, the slot or depression 20 at the forward end of said valve may be made to register with the hole 15 to a greater or less extent, or it may be turned so far to either side of said hole as to effectually prevent the escape of any oil whatsoever.

Upon reference to Figs. 1, 2, and 4, it will be seen that a channel of uniform depth is at all times afforded for the discharge of the oil, regardless of the width of said discharge. It is found in practice that the oblong opening possesses material advantage over an annular opening of the same capacity, as it is less liable to become clogged up with sediment.

Heretofore it has been customary to provide injector-burners with a hollow valve adapted to fitinto a circular valve-seat, the oil being admitted about all sides of the valve; but such a plan is objectionable, because of the clogging of the opening by sediment in the oil when the valve is adjusted close to its seat. Under my construction this difficulty is overcome, as I have at all times a passage or outlet of uniform depth, only the width of the passage being varied to regulate the oil-supply.

I make no broad claim herein to the wormwheel and worm for operating the hollow valve, as that idea is embraced in an application led by me March 3, 1887, Serial No. 229,599, the present invention, so far as it relates to the means for operating the hollow valve, being restricted to the precise arrangement shown and claimed.

Having thus described my invention, what I claim is- 1. In combination with case or shell 1, provided with discharge-nozzle 3, steam-inlet 6, and oil-inlet 15, a hollow valve, 7, provided with steam-inlets 19 and a longitudinal slot or depression, 20, a valve-stem, 12, mounted within the hollow valve 7, and means for rotating the valve 7, all substantially as shown and described. Y

2. In combination with case or shell 1, having steam-inlet 6 and oil-inlet l5, a conical dis- .tially as shown charge-nozzle, 3,' a hollow valve, 7, provided with steam-inlets 19 and with a tapered end, a longitudinal depression, 20, formed in the outer face of the conical end, a conical discharge-'outlet also in the end of the hollow valve, means for rotating the hollow valve,and a valve-stem provided with a tapered nose,22, to Iit into the discharge-outlet of the hollow val ve, all substantially as shown.

3. In combination with case or shell 1, having steam and oil inlets 6 16, a discharge-nozzle, 3, a hollow valve, 7, provided with a longitudinal slot or depression, 20, an opening,

the valve and serving' to convey the oil from the oil-inlet 16 to the depression 20, a valvestem, 12, mounted within the hollow valve, and means for rotating the hollow valve, all combined and arranged substantially as shown.

4. In combination with case or shell 1, having steam and oil inlets and a discharge-nozzle, a hollow valve, 7, provided with a central steam-discharge outlet and with a longitudinal depression, as 20, to register with the oilinlct, a worm-wheel, 5, secured to said hollow valve, a Worm, 10, mounted in the casing to engage with said worm-wheel, and a valvestem, l2, mounted within the hollowV valve and arranged to regulate the discharge of steam therefrom.

5. In combination with case or shell 1, provided with suitable steam and oil inlets, adischarge-nozzle, a shoulder, as 27, and a transverse enlargement, as 23, a hollow Valve, as 7, provided with an internal stem, 12, a wormwheel, 5, secured upon the valve 7, adapted to turn therewith and resting against or in prox- -imity to the shoulder 27, a worm, 10, mounted in the enlargement 23 to mesh with the wormwheel, and a cap, as 4, screwing into the end of the shell or case and serving to retain -the worm-wheel in position.

6. In an injector-burner, the combination,

7. In an injector-burner, the combination, with the case or shell 1, constructed substantially as shown, of the hollow valve 7, the screw-stem 12, and worm-gearing 5 10, located wholly within the casing, for rotating the hollow valve.

8. In an injector-burner, the combination, with a case or shell provided with suitable oil and steam inlets and a discharge-nozzle, of a hollow valve mounted therein and means for rotating the same, a spring arranged substanto hold the valve to its seat,

and a valve-stem adjustable within the hollow valve.
